Real-World Haptics: Reproduction of Human Motion

In recent years, communication technologies have grown rapidly and from the communication point of view, real-world haptics is the key technology for future haptic technology. Consequently, this article focuses on the storage and reproduction methods for haptic information in the real world. The bilateral connection of haptic systems with force feedback ability makes telecommunication among remote human operators possible. This article shows a motion-copying system (MCS) as a spatiotemporal coupler of real-world haptic information. As with sound and visual information, an MCS is capable of storing and reproducing raw force and position information of human operator. Once human motion is stored using MCS, it is possible to reproduce it at any time and place. This will be useful for the digital preservation of motions by skilled experts as a haptic database.
